Hi Mark,

Mark H Weaver <mhw <at> netris.org> skribis:

> I just ran the following command on my Thinkpad X200 running GuixSD:
>
>   ./pre-inst-env guix environment guile --ad-hoc autoconf automake libtool flex gettext
>
> Using the guix client from a git checkout at v0.13.0-1496-gcfd6a3b1e,
> and using guix-daemon from guix-0.13.0-3.b547349.
>
> This command took approximately 20 minutes of CPU time before
> downloading anything except possibly some NARINFOs.  During this initial

Is it reproducible?  If/when that happens again, could you ‘strace’ the
‘guix substitute’ process?

Any idea whether hydra.gnu.org was loaded at the time and returning 504
(“Gateway Timeout”)?

Thanks,
Ludo’.
